Back of bottle of Wazine says that it's not for egg laying birds. Folks here say to just wait 2 weeks and then eat the eggs because the wait time for butchering after using Wazine is two weeks. However, there are more than two weeks worth of eggs in a hen that are developing and some breeding experts indicate that it takes 4 weeks to clear eggs fertilized by one rooster out of the hen before mating her with a new rooster. So, of course, I could just wait 4 weeks after Wazine use. But I am wondering if anyone knows of any documentation showing why the Wazine bottle says that we shouldn't give Wazine to any egg layer. What do the manufacturers know? Also, is there anyone that can point me to evidence that Wazine is out of an egg layer's eggs at two weeks after taking Wazine. I'd like maybe a notation in a Vetrinarian book or something like that. Also, is there any documentation detailing the side effects of Wazine like there are for human drugs. You know, like on TV when they advertise a drug and then tell you that you may possible have kidney failure, asthma, hardening of the artieries, lymphoma, uncontrolled urination, etc.
